The original diagnosis for Royals catcher Salvador Perez has been confirmed.

According to a report from MLB.com, the six-time All-Star will undergo Tommy John surgery Wednesday to repair ligament damage in his right elbow.

Perez suffered an undisclosed injury to his right elbow last Wednesday and according to an initial report, Tommy John surgery was on the table but wasn't necessary. He later sought out the second opinion of Dr. Neal S. ElAttrache, who confirmed he would undergo the procedure.

Salvador Perez's second opinion from Dr. ElAttrache confirmed original diagnosis. Perez will have Tommy John surgery tomorrow.

The team has not offered any details on how Perez suffered the injury. But talks of his replacement are reportedly taking place.

MLB Network reported that Kansas City already has been in touch with free agent Martin Maldonado.

Perez has a career slash line of .266/.297/.442 and has averaged almost 18 home runs and 63 RBIs in his eight-year MLB career. He has caught 35 percent of attempted base-stealers and has a career .995 fielding percentage.
